Assuming you want to sort the files in place and you don't have any hard links or non-default file modes or group-IDs you need to preserve in your .las files, a simple loop of the cjcox's suggestion should do what you want:
If you want new files created instead of replacing the original files, try:

Hello,
I have a header which I have to add to a sorted file, however if I use
cat header sortedfile > newfile, the operation takes 2 minutes as the sorted file is over 400mb.
I have noticed that when I sort the 400mb unsorted file, this only takes 14 seconds to create the output.

So, I have a file that has some duplicate lines. The file has a header line that I would like to keep at the top.
I could do this by extracting the header from the file, 'sort -u' the remaining lines, and recombine them. But they are quite big, so if there is a way to do it with a single... (1 Reply)

check-permissions
check-permissions(1M) System Administration Commands check-permissions(1M)NAME
check-permissions - check permissions on mail rerouting files
SYNOPSIS
/usr/sbin/check-permissions [login]
DESCRIPTION
The check-permissions script is intended as a migration aid for sendmail(1M). It checks the /etc/mail/sendmail.cf file for all configured
alias files, and checks the alias files for :include: files. It also checks for certain .forward files. For each file that check-permis-
sions checks, it verifies that none of the parent directories are group- or world-writable. If any directories are overly permissive, it is
reported. Otherwise it reports that no unsafe directories were found.
As to which .forward files are checked, it depends on the arguments included on the command line. If no argument is given, the current
user's home directory is checked for the presence of a .forward file. If any arguments are given, they are assumed to be valid logins, and
the home directory of each one is checked.
If the special argument ALL is given, the passwd entry in the /etc/nsswitch.conf file is checked, and all password entries that can be
obtained through the switch file are checked. In large domains, this can be time-consuming.
OPERANDS
The following operands are supported:
login Where login is a valid user name, checks the home directory for login.
ALL Checks the home directory of all users.
FILES
/etc/mail/sendmail.cf Defines enviornment for sendmail
/etc/mail/aliases Ascii mail aliases file
